- the clamp block 123 is fastened to the support rod 113.
- the auxiliary clamp block 132 is lifted by a length HI corresponding to the length of the auxiliary clamp block 132 above the clamp block 123 by loosening and lowering it, and the force is again tightened to the support rod 113.
- the support rod 113 is lowered by the mass of the component supply device 82, and the auxiliary clamp block 132 is received above the stationary clamp block 123, and the lowered position of the component supply device 82 is set. Is done.
- the lowering work is completed by tightening the clamp block 123.
- the lowering amount HI of the component supply device 82 can be set simply by moving the auxiliary clamp block 132 upward by a predetermined length HI, and the supporting rod 113 can also be used to supply the component.
- the device 82 can be lowered by its own weight, and the auxiliary clamp block 132 acts as a stop, and the lower limit position of the lowering is set. Therefore, the work is easy and the descending amount HI can be set accurately, and the work is simplified and the work is safe.
- the auxiliary clamp block 132 is also provided below the clamp block 123 as shown by the two-dot chain line, the auxiliary clamp block 132 is raised after the lowering operation is completed, and Closely adhere to the lower side and tighten to the support rod 113.
- FIG. 23 shows an operation sequence when the component supply device 82 is raised. Initially, clamp block 123 is tightened. Next, the auxiliary clamp block 132 is lowered by a length H2 corresponding to the length of loosening and raising the lower auxiliary clamp block 132 on the lower side of the clamp block 123, and the support rod 113 is tightened again. Then When the ramp block 123 is loosened and the component supply device 82 is lifted, the support rod 113 is raised, and the auxiliary clamp block 132 is received by the lower portion of the stationary clamp block 123, and the ascending position of the component supply device 82 is set. . Finally, the clamp block 123 is tightened to complete the lifting operation.
- auxiliary clamp block 132 In this way, simply moving the auxiliary clamp block 132 downward by a predetermined length H2 can set the rising amount H2 of the component supply device 82, and furthermore, simply lift the component supply device 82. Can raise the support rod 113, and the auxiliary clamp block 132 functions as a stop, and the upper limit position of the lift is set. Therefore, the work is simple and the amount of rise H2 can be set accurately, and the work is simplified and the work is safe. If the auxiliary clamp block 132 is also provided above the clamp block 123 as shown by the two-dot chain line, the auxiliary clamp block 132 is lowered after the lifting operation is completed, and Make tight contact and tighten to support rod 113.
- the configuration of the clamp block and the auxiliary clamp block described above is used for adjusting the vertical position of the vertical portion 120 at the position of the coupling block 122 shown in FIG.
